looking has begun....
I have seen the file and from my Monitor, it appears that everything is or has properly updated (however I opened it in R2009 as I do not seem to have a(n) 2008 version handy to test it in ATM)
and may be a version specific issues; suggested remedy Remove all the new corridor regions, rebuild, and then add them back in and verify that the section group, and views did/not update correctly on that pass.
